The North American International Auto Show--more commonly known as the Detroit Auto Show--is officially opening its doors this week. One of the exhibitors, of course, is German carmaker Audi, whose main attraction at its booth will be this Allroad Shooting Brake concept vehicle. ("Shooting brake," by the way, is an old British term for "station wagon.") This futuristic and stylish rendition of the otherwise boring wagon is made even sportier by the fact that it only has two doors and flaunts a very cool Ice Blue paint job.

The Allroad Shooting Brake is a plug-in hybrid car. Its hybrid system, which has an overall output of 408hp and an overall torque of 650Nm, consists of a 2.0-liter four-cylinder TFSI turbocharged engine (292hp and 380Nm) and two electric motors. The main electric motor, integrated in the six-speed e-S Tronic transmission, is rated at 40kW and 270Nm. A second electric motor, separate from the drive unit, is mounted to the rear axle and contributes 85kW and another 270Nm.

The car's lithium-ion battery, located just forward of the rear axle, has eight modules and an energy capacity of 8.8kWh, said to be enough for 50km of all-electric driving. The Allroad Shooting Brake is also touted to reach 100kph from rest in just 4.6 seconds, with an electronically limited top speed of 250kph.

In its concept car form, the Allroad Shooting Brake weighs 1,600kg, good for an average fuel consumption figure of 1.9L of fuel per 100km (or an astounding 52.6km/L). The car's sheet metal is a mix of aluminum and carbon fiber reinforced polymer. The underbody protection visible from the rear is also made of aluminum.

And the wheels? They measure a generous 19 inches and are wrapped in 255/40 rubber.
